Key Features of the PSP Precision Port

  • Greater Sound Pressure Levels: The "PSP Precision Port™" can add an average of 3db in output if used correctly.
  • Cleaner Sound - Less Distortion: No turbulence at entrance or exit of port.
  • Cosmetically Appealing: The mounting flange on the outside flare has been textured to be more appealing to the eye.
  • Adaptability: Can be used in any type of ported enclosure as long as you have left a minimum diameter of 5.25" for 2" ports, 6.25" for 3" ports, 7.25" for 4" ports, and 9.25" for 6" ports.
  • High Quality ABS Construction: In order to obtain a high quality part we utilize injection and extruded molding processes. This allows PSP to achieve closer tolerances so all parts will fit properly.
  • Easy Installation: Due to the design of the 3" and 4" PSP Precision Ports you can simply cut your port hole to the same diameter as the flared end of the inside port, drop the assembled port in and either glue or screw it down. No need to use round-over routering and back filling. Currently PSP manufactures 2", 3", 4", and 6" sizes. Due to the modular design we have incorporated into our product you can achieve port lengths from 4" on the 2" PSP Precision Port and 5" on the 3", 4" , and 6" PSP Precision Ports, flares only with 1 connecting ring, to any length you need by adding lengths of tubing and connecting rings.
  • Mounting Hole Variations: The mounting flange on the 3" and 4" outside flare is made with predrilled holes. The 2" and 6" outside flares have recessed drill bit guides on the back of the flange if you want to drill mounting holes. The 2" and 6" also have a ring on the back side of the outside flare to help secure the flare in the enclosure.
